DESCRIPTION
In kernel space, each rtapi_xxx or RTAPI_XXX identifier is mapped to the underlying kernel functionality, if available. In userspace, or in kernels where the underlying functionality is not provided by a kernel, generally another implementation--possibly with reduced functionality--is provided. (For example, the userspace implementation for rtapi_pci_register always succeeds)

REALTIME CONSIDERATIONS
Typically, these functions may be called from realtime init/cleanup code.

RETURN VALUE
As in Linux.
